Definitions

  • This invention relates to valve guides for use in cylinder heads of internal combustion engines, more particularly it refers to valve guides that are used in cylinder heads constructed of aluminum, magnesium or other non-ferrous materials.
  • valve guides in cylinder heads is a particular problem since alignment and resistance to loosening and pullout are critical to proper engine performance.
  • valve guides were often made an integral part of the cylinder head by inserting them into dies or molds and casting the cylinder head around them. After cooling alignment with valve seat is achieved by drilling out the center of valve guide in proper angular relationship. This requires extreme precision in the drilling and positioning of parts and is a difficult operation in high volume engine manufacture.
  • Another object of the invention is to provide a more simple and improved valve guide.
  • a further object of the invention is to provide a valve guide that is self locking upon alignment and installation into a fixed position.
  • Still a further object is to provide a valve guide that can be easily removed and replaced utilizing standard tools available in the automotive industry.
  • FIG. 1 is a cutaway prospective view of the device embodying feature of the present invention.
  • FIG. 2 is a view in elevation of the valve guide of this invention partially installed in a cylinder head.
  • FIG. 3 is a view in elevation of the valve guide of this invention installed in a cylinder head.
  • FIG. 4 is a magnified cross-section through 3--3 of FIG. 3.
  • FIG. 2 The structure selected for illustration is shown in association with a cylinder head housing 10 which has been suitably bored 11 for reception of a customary valve guide.
  • the valve guide of this invention is shown in FIG. 2 partially installed.
  • the valve guide consists of a cylindrical body 20 containing a beveled pilot edge 21 at the foreward end thereof to lead the valve guide easily into the prebored hold during installation.
  • annular ring 22 Located back from the lead edge at a distance greater than 1/4 of the total length of and less than 1/3 of said distance in an annular ring 22 which is dimensioned to size the prebored hole and position the guide in relation to the valve insert. While the preferred embodiment includes the annular ring 22, it may be omitted and the prebored hole drilled to receive the body 20.
  • An annular groove 23 is formed by shoulder 24 of cylinder body 20 and a forming shoulder 25 of serrated (28, 29) locking flange 26 located near the opposite end of cylindrical body 20.
  • the balance of the cylindrical body 20 may be shaped as in 27 to accommodate an installation tool or other device, not shown.
  • the diameter of the forming shoulder 25 of the locking flange 26 is selected to flow the appropriate amount of metal from cylinder head 10 so as to pack annular groove 23 with sufficient material 30, FIG. 4 to form a metal to metal lock which would prevent axial movement and resist rotational movement.
  • the serrations may be omitted from the locking flange.
  • the locking flange shoulder 25 is of a greater diameter than that of the annular ring 22 or the cylinder body 20 if annular ring 22 is not used. The diameter is selected to flow the appropriate amount of metal from cylinder head 10 so as to pack annular groove 23 with sufficient material so as to form a metal to metal lock to prevent axial movement and resist rotational movement.
